Q on UMSWE

wanted to know how to put the model of a doodad on a unit. Can someone tell me all the icon and model codes
( doodads\xxxx\xxxx\xxxx ) or attach a document with them written on? Thx

If you have UMSWE you have all you nead.
Look at the folder called UMSWE Files in the War3 directory there is a file called All Models.txt

I'd suggest to load war3.mpq into a MPQ Editor (e.g.: WinMPQ) and set the filter to MDX. Then you see a list of all models.
